Answer:
The angle of depression for the flight part is approximately 0.2604 degrees
Step-by-step explanation:
The given altitude at which the helicopter is flying = 50 meters
The horizontal distance of the helicopter from the helipad = 11 kilometers = 11,000 meters
The angle of depression = The angle of elevation = Arctan(Altitude/(Horizontal distance)
Therefore;
The angle of depression for the flight part = Arctan(50/(11,000)) ≈ 0.2604 degrees
Answer: B and E are irrational numbers
x=80
The sum of interior angles in a quadrilateral is 360°
the square represents a right angle= 90 degrees
124+66+90=280
360-280=80
